Computed tomography (CT) of the abdomen is a procedure that employs computer-processed X-rays to create section images of the abdominal organs - liver, spleen, pancreas, lymph nodes and blood vessels.
CT of the gastrointestinal tract gives an idea of the structural peculiarities of the parenchymal organs and indicates any inflammatory processes, necrosis, perifocal (around the area) inflammation, as well as the sizes, position and shape of the organ. Abdominal CTs are used for the diagnosis of the diseases of the following organs:
- Liver – liver CT may show changes characteristic for primary benign and malignant tumors, secondary neoplasms and structural changes in the liver tissues
- Blood diseases – lymphoma and Hodgkin's disease
- Surgical diseases of the abdomen – appendicitis, abscess
- Helical computed tomography helps diagnose diseases of the abdominal vessels. It can also be used to study the intestine - virtual colonoscopy
In addition, magnetic resonance imaging can be used to study the abdomen and diagnose pancreatic or liver diseases (cirrhosis). It uses magnets and radio waves to create images of the abdominal structures and organs.
Computed tomography should be carried out on an empty stomach.
